Uwe Kleine-König 2ac2793f8d media: m5mols: Convert to i2c's .probe_new()
The probe function doesn't make use of the i2c_device_id * parameter so it
can be trivially converted.

Uwe Kleine-König ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Mauro Carvalho Chehab 9958d30f38 media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

Linus Walleij aaaf357fa6 media: m5mols: Convert to use GPIO descriptors
The Fujitsu M5MOLS sensor driver is using a reset GPIO number
passed from platform data.

No machine/board descriptor file in the kernel is using this so
let's replace it with a GPIO descriptor.

Tomi Valkeinen 0d346d2a6f media: v4l2-subdev: add subdev-wide state struct
We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.

I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.

This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.

The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:

dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done

Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

Mauro Carvalho Chehab 32a363d0b0 media: Kconfig files: use select for V4L2 subdevs and MC
There are lots of drivers that only work when the media controller
and/or the V4L2 subdev APIs are present.

Right now, someone need to first enable those APIs before
using those drivers.

Well, ideally, drivers, should, instead *optionally*
depend on it, in order for PC camera drivers to be able to use
them, but nowadays most drivers are UVC cameras, with don't
require a sensor driver.

So, be it.

Let's instead make them select the MEDIA_CONTROLLER and the
SUBDEV API, in order to make easier for people to be able
of enabling them.

Sakari Ailus 654be7dde7 media: v4l: i2c: Add a comment not to use static sub-device names in the future
A number of sub-device drivers used a static name for the sub-device, and
thus the media entity. As the entity name must be unique within a media
device, this makes it impossible to have more than one instance of each
device in a media device. This is a rather severe limitation.

Instead of fixing these drivers, add a comment to the drivers noting that
such static names may not be used in the future.

The alternative of fixing the drivers is troublesome as the entity (as
well as sub-device) name is part of the uAPI. Changing that is almost
certain to break something. As these devices are old but no-one has
encountered a problem with the static names, leave it as-is.

Mauro Carvalho Chehab ab22e77cd3 [media] media framework: rename pads init function to media_entity_pads_init()
With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.

So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.

The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

So, rename the field as function.

Please notice that this patch doesn't extend support for

Mauro Carvalho Chehab 1809510715 [media] media: get rid of unused "extra_links" param on media_entity_init()
Currently, media_entity_init() creates an array with the links,
allocated at init time. It provides a parameter (extra_links)
that would allocate more links than the current needs, but this
is not used by any driver.

As we want to be able to do dynamic link allocation/removal,
we'll need to change the implementation of the links. So,
before doing that, let's first remove that extra unused
parameter, in order to cleanup the interface first.

Mauro Carvalho Chehab b5dcee225c [media] include/media: split I2C headers from V4L2 core
Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.

Let's move those i2c specific files to its own subdirectory.

The files to move were produced via the following script:
	mkdir include/media/i2c
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	for i in include/media/*.h; do n=`basename $i`;  (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done

And the references corrected via this script:
    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="i2c/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;

			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";

Hans Verkuil f7234138f1 [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config
If a subdevice pad op is called from a bridge driver, then there is
no v4l2_subdev_fh struct that can be passed to the subdevice. This
made it hard to use such subdevs from a bridge driver.

This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
pointer in the pad ops. This allows bridge drivers to use the various
try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
along to the pad op.

The v4l2_subdev_get_try_* macros had to be changed because of this, so
I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
'git grep v4l2_subdev_get_try_format' you will actually find the header
where it is defined.

One remark regarding the drivers/staging/media/davinci_vpfe patches: the
*_init_formats() functions assumed that fh could be NULL. However, that's
not true for this driver, it's always set. This is almost certainly a copy
and paste from the omap3isp driver. I've updated the code to reflect the
fact that fh is never NULL.

The be16_to_cpu conversions in m5mols_get_version() are not needed since the
data is already using cpu endianness. This was never noticed since these
version fields are never used.

The include/media/s5p_fimc.h header has been removed in commit
49b2f4c56f ("exynos4-is: Remove support
for non-dt platforms"). This broke compilation of the m5mols driver.

Greg Kroah-Hartman 4c62e9764a Drivers: media: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

It prevents possible build errors due to undefined SZ_1M.
